Jeff Rowland Model 7 serie II

[Syl20]

Hello all,

I have a pair of serie 2 in my possession and I plan to serviced them (monoblocs work well but after more than 20 years ...). I'm looking for any kind of information (or person who has information) for doing that. I am really not for sending them in US (JeffRowland), these power amps are very heavy ( very expensive shipping cost + transport risks).
Regarding some of information I'm looking for (if possible) :
Reference of capacitors to replace 22000µf 100V (not on pictures)
Reference of capacitors to replace sprague 100µf 200V (on pictures)
Any small component like electrolytics, resistors ...

I tried to take some picutres of inside power amps, I can take others if needed.
Many thanks for your help.

Sylvain

I would measure the diameter, pin pitch for the PCB mounted ones, and length of the caps to make sure the new ones fit, then check Mouser or Digikey for the value and verify the size.
Then order.

Full recapping will be very expensive commensurate to the value of the amps. If the old caps are ok rather leave them alone. Both Rifa and Kendeil make suitable caps for the main filter.
